A portable low profile mechanical scale is provided having a carriage with spaced side frames each with wheel means at one end and ground support means at the other end, spacers between the side frames holding them in fixed parallel relation, removable wheeled lift means engaging the side frames adjacent the ground support means for moving the side frames, a pair of torsion bars above said side members at two different parallel levels, one adjacent each side frame and supported thereon by triangular links fixed to the torsion bars at one end and supported on the side members at the other, a weigh bed movable vertically between the side frames and pivoted to the triangular links between the torsion bar and support on the side frames, a lever on each torsion bar adjacent said wheel lift means extending transversely toward each other, one above the other, a link connecting said levers midway between the side frames and a connector on the uppermost lever for connecting to a weight indicating mechanism.
